Debris Elimination In A Droplet-target Laser-plasma Soft-x-ray Source
(1995) In Review of Scientific Instruments 66(10). p.4916-4920- Abstract
- A tabletop high-brightness line-emitting laser-plasma soft xray source utilizing single microscopic droplets as target is shown to produce several orders of magnitude less debris than conventional-target sources. Quantitative measurements of debris deposition rates and x-ray flux, at different directions around the droplet plasma are presented. With ethanol droplets and a. 10 Hz. 70 mJ/pulse laser, typically similar to 1 x 10(12) photons/(sr . pulse . line) are emitted from the C V and C VI lines in the water window. The debris deposition is further reduced with a small, localized gas jet shield. which is transparent to the x-rays. The deposition rate through the gas shield has been determined to be similar to 0.2 pg/(sr . pulse). Thus,... (More)

Thus, this droplet-target laser-plasma x-ray source is four orders-of-magnitude cleaner than a low-debris plastic tape target laser plasma of similar brightness, making it useful for x-ray microscopy and lithography.
